As one of the most important type of gold deposits, hydrothermal gold deposit has become the hot research area of mineral deposits at present and for a long time to come because of its great economic value and ore-prospecting potentials. Mathematical statistics on mineralization abundance, including grade and linear productivity, of a hydrothermal gold deposit in Jiaodong Peninsula, were done. The results show that mineralization abundance of the hydrothermal gold deposit follows lognormal distribution which is consistent with traditional research findings, which have academic significance for further studies on hydrothermal gold mineralization characteristics and deposition mechanism. © (2013) Trans Tech Publications, Switzerland.

Visible light responsive In2O3/rectorite composite was successfully synthesized via a facile and low-cost precipitation method. The as-prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption/desorption measurements and UV-vis diffuse reflectance spectra (UV-vis DRS). The ordered structure of rectorite was destroyed to some extent and the size of In2O3 particles is about 10-40 nm. The specific surface area of the In2O3/rectorite was reached to 198.51 m2/g. The absorption edges of the IR samples (about 460 nm) display a noticeable shift to the visible light region as compared to that of the In2O3 (355 nm). The In2O 3/rectorite photocatalyst prepared at 500 C for 4 h showed a strong adsorption capability and a high visible light photocatalytic activity for acid red dye, which could be attributed to the synergetic effects of the rectorite structure and the In2O3. © 2013 Published by Elsevier B.V.
